Token for top-level window to move.

window manager, if there is one.

<H3><A NAME="M5">DESCRIPTION</A></H3>
In general, a window should never set its own position;  this should be
done only by the geometry manger that is responsible for the window.
For top-level windows the window manager is effectively the geometry
manager;  Tk provides interface code between the application and the
window manager to convey the application's desires to the geometry
manager.  The desired size for a top-level window is conveyed using
the usual <B><A HREF="../TkLib/GeomReq.htm">Tk_GeometryRequest</A></B> mechanism.  The procedure
<B>Tk_MoveToplevelWindow</B> may be used by an application to request
a particular position for a top-level window;  this procedure is
similar in function to the <B><A HREF="../TkCmd/wm.htm">wm geometry</A></B> Tcl command except that
negative offsets cannot be specified.  It is invoked by widgets such as
menus that want to appear at a particular place on the screen.
<P>
When <B>Tk_MoveToplevelWindow</B> is called it does not immediately
pass on the new desired location to the window manager;  it defers
this action until all other outstanding work has been completed,
using the <B><A HREF="../TclLib/DoWhenIdle.htm">Tcl_DoWhenIdle</A></B> mechanism.
